PACKING MECHANISM FOR OIL AND WATER WELLS.

Specification of Letters Patent.

Patented Feb. 9, i915.

Application led December 4.-, 1912. Serial No. 734,825.

The object of the invention is to provide a mechanism of the character described designed to be used in wells for the purpose of casing off water. s

As is well known, in boring an oil well a water vein is often encountered as well as oil and the water becomes mixed with the oil and otherwise interferes with the boring of the well.

`It is the object of this invention to provide a device whereby the water may be entirely cased off from the oil so that it will not become mixed therewith or escape into the bore and be discharged to the surface.

With the above and other objects in view the invention has particular relation to certain novel featuresof construction, operation and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawings wherein:

Figure 1 is a Sectional side elevation of the device showing the position it will assume when vit is in use, the inclosing fabric being removed so as to expose the rib. Fig. 2 is a sectional side elevation showing the position it will assume when being lowered into or withdrawn from the Well. Fig. 3 is a sectional view of the device taken on the line a-a of Fig. 1, and showing the same in the position as shown in Fig. 1, a portion of said device being broken away. Figs. 4: and 5 show a plan and edge view respectively of one form of the supporting ribs used in the construction of the device, and, Figs. 6. and7 show plan and edge views respectively of another form of ribs employed. Y

Referring now more particularly to the drawing wherein like numerals of reference designate similar .parts in each of the figures the numeral 1 designates the upper section of the pipe through which the oil is con'- ducted` from the bore; connected to this section is a short pipe sectiow2 of considerably larger diameter, these two sections being united by ,means of a reducing nipple 3, this nipple being connected to the respective pipe sections 1 and 2 by means of the ordinary collars 4s and 5. Extending up into the pipe section 2 from beneath is another pipe section 6 considerably smaller in diameter than section 2 which carries an enlarged head or collar 7 at its upper end, said head fitting closely in the section 2 and closely surrounding said section 6 is an outwardly .threaded cuff 8 which is designed to be screwed up into the inwardly threaded lower end of section 2 and to prevent the withdrawal of the head 7 from the said section 2. Closely surrounding the section 6 and4 beneath the cuff 8 is a. sliding collar 9 which has free vertical movement relative to section 6 but whose downward movement is limited by means of the annular shoulder 10 which is integral with the section 6 and arranged beneath the collar 9; pivoted to the lower end of the cuff 8 and radiating there from are a plurality of inflexible ribs 11 and pivoted to the upper end of the sliding collar 9 and radiating therefrom are a corresponding number inflexible radiating ribs l2; the outer free ends of the respective ribs 11 being hinged to the outer ends of tlie corresponding ribs 12, as shown in Figs. 1 and 2. These ribs are covered on the out-4 side by means of a strong oiled fabric covering or some similar strong flexible material ,1 this covering is secured in place on the ribs in any preferred manner as by being sewed thereto or in any other way which may be preferred.

When a stream of water has been encountered and it is desired to case the same off and stop the flow thereof up into the bore, the device is assembled as shown and attached to a string of pipe of sufficient length to bring the casing device to the p roper point when the pipe has been lowered 1n the bore. AThe upper section 1 is then forced .vents the water of one side. thereof from mingling with the oil of the other side. The

detritus in the fluid and earth and other matter will gradually collect between said ribs and finally completely block the bore and entirely cut off the flow of fluid from one side of the device to the other.

W hat I claim is:

'1. A device of the character described composed of two pipe sections, one telescoping within the other, said sections having a continuous 'fluid passageway therethrough and being securedl together so as to be freely slidable lengthwise relative to each other, a collar upon the inner section, a plurality of ribs pivoted to the outer section and a plurality of ribs pivoted to the collar, the free ends yof the corresponding ribs of the two 'series being hinged together, said ribs being inflexible and projecting outwardly at approximately right angles to the pipe when f the outer section is forced against the collar.

2. A device of the character described sections and surrounding said ribs andl adapted to be forced outwardly from said sectionsby said ribs. r

3. A device of the character described including an upper anda lower pipe section, said sections being slidably secured together, a collar upon the lower pipe section, a lurality of ribs pivoted to the lower end o the upper pipe section, a corresponding number of ribs pivoted to .said collar, the corresponding ribs being hinged together in such a manner that the said ribs will project out from the pipe at approximately right angles when the upper section is forced against said collar and a covering composed of flexible material impervious to the passage of fluid enveloping said ribs. r 'l 4. A device of the character described including an upper and a lower pipe section, said sections telescoping and being secured together, so as to be freely movable lengthwise relative to each other, a collar upon the lower pipe section, a vplurality ofy hinged members, each lof which is secured at one composed of telescoping pipe sections having cluding upper and lower pipe sections, the' lower' of said sections telescoping into the upper section and the sections being movable lengthwise relative to each other and having a continuous fluid passageway there-v through, an enlarged head carried by the free end of the lower section and a cuff threaded into the free end of the upper section, so as to lock against said head and prevent the separation of the sections, a collar upon the lower pipe section, a plurality of inflexible ribs pivoted to the lower end of said cufl'I and,a corresponding number of similar ribs pivoted to the upper end of said collar, the corresponding ribs being hinged together, said ribs being arranged to project outwardlyv as said collar and cufl:` are forced together.

6. A device of the character described, including upper and lower pipe'sections, the lower of said sections 4telescoping into the upper section, and the sections being freely movable lengthwise relative to each other and having a continuous fluid passageway therethrough, an enlarged head carried by the free end of the lower section and a cuff threaded into the free end of the upper section, so as to lock against said head and prevent the separation of the sections, a collar upon the lower pipe sections, a plurality of inflexible ribs pivoted to the lower end of said cuff and a corresponding number of similar ribs pivoted to the upper end of said collar, the corresponding ribs being hinged together, said ribs beingarranged to project outwardly as said collar and cuff are forced together, and a flexible covering surrounding said ribs and secured above and below the ribs to the respective pipe sections.

'7. A device of the character described including upper and lower pipe sections, the lower'of said sections telescoping into the upper section and the sections bemg freely movable lengthwise relative to each other and having a continuous fluid passageway therethrough, an enlarged head carried by the free end of the lower section, a cuff threaded ,into the free end of the upper section, so as to lock against said head and prevent the separation of the sections, a collar upon the lower pipe section, a plurality of inflexible ribs pivoted to the lower end of said cuff, a corresponding number of similar 'ribs pivoted to the upper end of said collar,

the corresponding ribs being hinged .toi

gether, saidribs being arranged to roject outwardly, elbow -fash1on, as said co ar and cuff `are forced to ether and fold one toward the other and a exible covering surrounding said ribs and secured above and below the ribs to the respective pipe section.

8. A device of the character described composed of two telescoping pipe sections, having a fluid passageway therethrough and secured together so as to be freely slidable lengthwise relative to each other, two series of ribs, the ribs of one series being pivotedto one section and the ribs of the other series having engagement with the other section,

. the corresponding ribs of the two series being hinged together in such manner as to allow the said corresponding ribs to fold one toward the other, and Iproject out at approximately right angles to the pipe.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
